Error -1607: Unable to Install InstallShield
Scripting Run Time

This error most commonly occurs
when there are insufficient access rights during
installation.

you are logged on with admininstrative rights and that there
are no restrictions in place that might prevent the installer
from operating (examples include network group policies and
anti-virus software protection)
and run the installer again.

Error -1608: Unable to Create InstallDriver
Instance

This error most commonly occurs
when there are insufficient access rights during
installation.

Try ensuring that
you are logged on with admininstrative rights and that there
are no restrictions in place that might prevent the installer
from operating (examples include network group policies and
anti-virus software protection)
and run the installer again.

The most likely cause of a 1628
error would be if one accidentally tried to run the installer
more than once at the same time.

Try removing the
installation CD and then restarting your computer. Once the
computer has restarted, re-insert the CD and wait for the
CD menu to appear. When the menu appears, click just once
with the left mouse button on the top installation option.
You should now wait for the installation to start. Note that
depending on the speed of your computer, there can sometimes
be a delay between clicking on the CD's install option and
the actual installation window
appearing on the screen.
